Sudoku

To those lacking inherent appreciation of DICSS I offer an altogether beautiful and touching alternative.

Building

Run cargo build --release and then copy the /resources folder to the directory of the generated EXE.

Runtime dependencies

The application runs on all platforms that can be targeted by Rust. Rendering the GUI requires OpenGL support. The specific compiler runtime dependencies need to be installed if building dynamically.

Implementation details

The GUI is built on top of Conrod v0.61.1 as to me it seemed the simplest, easiest-to-use GUI library for Rust at the time of selection.

The game features four difficulty levels: easy, medium, hard and very hard, and it comes with fourty predefined games in each - see /resources/games/*.sud; these files can be modified and / or expanded to include more games. The provided predefined games were generated using the online game generators of Open Sudoku.

The game-solving algorithm is a direct adaptation of /other/solver_algorithm/solve_board_algorithm.cpp, which comes from GeeksforGeeks.

As for code organization, there are two important submodules of the binary root module:

• The responsibilities of the game module are new game selection, error-checking logic, solver algorithm, game saving, and there are unit tests for some of the algorithms.

• The gui module provides a thin interface for the root module and handles some of the usual setup with Conrod, its logic submodule and this module's sudoku_board custom widget submodule is where the game GUI is created.
